I haven't ever used Illustrator before, but this ad caught my eye. I love the message.
Update: as of 6.12.13 I"m still working on my ad. I actually just started in on it yesterday and have made some progress with the wording, and the hands. I'm afraid this is going to take FOREVER because I've been using the pen tool to create all the "Bla"'s seperately. I tried making one and then copy/pasting and resizing but many of the letters are more different than they appear, so its slow going. In hindsight I would have chosen something less busy but at least I'll get lots of practice this way!
